Going to have a go for the series:
Boland: 10/10 - couldn't have asked for much more from him, once again excelling when given his chance. His bowling at Sydney was magnificent and was decisive in a strongly contested match. Even batted well at Melbourne.
Cummins: 8/10 - wanted to give him 9/10 with his batting contributions, but his woefully ill-prepared performance helped hand the Perth match to India. Bowled well in the remainder without seeming quite back to his absolute best, and made some good runs. He's a good leader and cool head. While improved tactically I think he still lets things drift, but he's gotten more ruthless at exploiting breakthroughs once they happen.
Carey: 6/10 - kept tidily, much more so than his counterpart, and provided some good starts with the bat when needed, most notably at Perth and Sydney. His only fifty coming at Brisbane continued a frustrating tendency to not make a bigger score unless someone else has.
Head: 9/10 - the leading run scorer in a difficult series and proving himself once again to be a player of impactful innings. The little downside is that he's still a bit inconsistent.
Khawaja: 3/10 - was inclined to a 4, but went lower. Bumrah clearly had his measure, though he looked more comfortable facing other bowlers. I think the end is very near though. No idea why he's fielding in the slips, except seniority and lack of mobility.
Konstas: 5/10 - His Melbourne innings was entertaining and disrupted Bumrah's rhythm for the only time in the series. But I think he overdid the aggression. Both dismissals at Sydney trigged collapses. He needs to try bat normally more, otherwise I worry he'll never live up to his potential. I don't think he willingness to get involved in conflicts was an overall positive either.
Labuschagne: 5/10 - maybe a bit generous. I think his three fifties were all good innings that he battled for, but he looked all at sea a lot of the time. He needs to consider technical changes to help combat his tendency to fish outside off.
Lyon: 4/10. His bowling figures for the series are actually better than I expected. The end is in sight, with action changes losing him a lot of zip and bounce, and his control was poor at times. Still managed to get some important wickets and some bonus batting at Melbourne.
Hazlewood: 8/10 - bowled beautifully at Perth but his side strain recurrence at Brisbane left us stranded (not that I think there would have been a result anyway). It's a real concern.
Marsh: 1/10. Only reason he gets any points is his three wickets and lost-cause 47 at Perth, and that he fielded well (unlike some others). But ultimately he proved a black hole in the order. After Perth he clearly wasn't fit to bowl, despite constant insistence otherwise, which threw a heavier workload onto the other fast bowlers.
McSweeney: 2/10. Debuting against Bumrah would severely test anyone, let alone someone who's not a specialist opener. Ultimately he failed the test. I think he's still good a potential future lower in the order and I hope he can put this behind him.
Smith: 7/10 - his two hundreds showed he's still got something left in the tank, and the Melbourne one was particularly good, but an overall average of 35 betrayed he scored nothing in between. I still think the Ashes next season should be his last series, and they should consider using him as a ring field.
Starc: 7/10 - I feel inclined to give him 6 simply for his second innings at Sydney. He bowled some magnificent spells, probably the best I've seen him bowl in tests. But he continued his inconsistency as well. I can't blame him for wanting to play at Sydney, but it's hardly a secret he conks out and he did here too.
Webster: 9/10 - in his only test he batted with a maturity rather lacking in the orders of either side. I think his bowling is probably too slow to be effective but he kept things tight enough and he caught well.
Ashwin: 2/10 - bowled economically if rather bluntly before deciding to throw in the towel mid-series. A terribly anticlimactic end to a great career.
Bumrah: 10/10 - absolutely magnificent and the main reason that each test was closer and more dramatic than the eventual margins indicated. He's lost a bit of pace and swing over the years, but his control and ability to seam the ball are as superb as ever and make him clearly the best bowler in the world at present for me. It is very unfortunate he basically had to bowl himself into the treatment room.
Deep: 3/10 - Bowled with more control than Rana, but was ultimately just as ineffective at actually getting wickets. Might have done better at Perth or Sydney if he'd got the chance.
Gill: 2/10 - three starts, nothing of substance. I think he's got the talent to be a very good batsman, but he's trying to prove otherwise.
Jadeja: 4/10 - played like a shadow of a formerly magnificent player. His 77 at Brisbane was a highlight but his bowling there was dreadful, possibly career worst. Bowled better at Melbourne but ultimately could not provide a decisive innings with the bat in the remainder of the series.
Jaiswal: 8/10 - a big ton at Perth to recover from the ignominy of a platinum duck and two good fifties, especially at Melbourne. But I think his aggression tended to get the better of him at times. Nonetheless I would be surprised if he isn't India's next great batsman, he's already had a wonderful start.
Kohli: 3/10 - hundred at Perth that made a likely winning target impregnable. Proceeded to spend the rest of the series getting out to painfully predictable off side wafts. Extra point off for reaching a new level at being a ****.
Krisha: 6/10 - very hard one to rate, took six wickets but some total gifts were included. Bowled okay I suppose but wouldn't be too good in less favourable conditions.
Jurel: 1/10 - does he look like a bat or keeper bat of potential? Maybe. Did he show that here? Definitely not.
Paddikal: 1/10 - looked out of his depth.
Pant: 5/10 - Not gonna lie that his batting scared me at times after the previous two series here, but the difference is that he kept getting out, sometimes with some seriously irresponsible shots. His knee seems to be preventing him playing as effectively and while I don't remember any egregious let offs, his keeping was scrappy.
Reddy: 8/10 - I found it amusing the Indian fans on here wanting him to be dropped after bailing out their top order again and again. His bowling seems no better than handy, being half a yard too slow. He's still young so it'll be interesting to see where his career goes from here.
Rahul: 6/10 - continued to be the KL Rahul we know and find frustrating. A lot of starts, two fifties, but no hundreds. After 58 tests it seems unlikely this will change. He'd be worth persisting with as opener if there were no better options available.
Rana: 2/10 - I remember before the series at least some India fans here insist he must be third seamer with Shami's absence. He bowled well enough amongst the carnage at Perth, but from then on showed he lacked control. No more than brisk fast-medium either.
Sharma: 0/10 - the clear
Marcus Harris of the series. Threw away his wicket at seemingly the first opportunity. Was outbatted by nearly everyone. Captaincy was baffling and shambolic. Would have been better off staying home.
Siraj: 4/10 - well I'd give him a 5 except he was that unpleasant. I think his bowling figures were flattering to him and he was Rubel Hossain bad at Melbourne. Some bowl better when fired up, he's not one of them.
Sundar: 3/10 - one good innings with the bat, bowled tidily in the small number of chances he got, one all-time bad piece of strike management that's worth a point off itself (yes surviving ten overs is hard. At least try). Unclear what his role in the team was supposed to be.
